SEAT CUSHION.

' Application filed January 22, 192$.v Serial No, 614,183.

My invention is disclosed in the followin full, clear and exactdescription, such as wil enable others skilled in the art to which itappertains to make and to use the same, reference being had to theaccompanying drawings which illustrate the preferred form of theinvention; though it is to be understood that the invention is notlimited to the exact details of construction shown and described, as itis obvious that various modifications thereof within the sco e of theclaims will occur to persons 'skille in the art.

In said drawings:

Fig. 1 is a plan view partly broken away of a portion of a seat cushionconstructed in accordance with" this invention, the upholstery beingremoved to show the spring construction Fig. 2 is a vertical section ofa seat cushion constructed in accordance with this invention, thesection being taken on the line 2-2 of Fig. 1;

Fig. 3 is a section taken on the line 3--3 of Fig. 1;.

Fig. 4 is a detail view showing a corner of the upper frame of thecushion;

Fig. 5 is a section taken on the line 55 of Fig. 4 looking in thedirection of the arrow;

Fig. 6 is a section taken on the line 5-5 of Fig. 4: looking in thedirection opposite to the direction of the arrow;

Fig. 7 is a view similar to Fig. 1 of a seat cushion of a modifiedconstruction;

Fig. 8 is a partial section of a cushion constructed as shown in Fig. 7,the section being takenon the line 8-8 of Fig. 7

Fig. 9 is a partial section of a cushion taken on the line 99 of Fig. 7looking in the direction of the arrow and Fig. 10 is a section throughthe upper frame of the cushion shown in Fig. 7 taken on the line 99 ofFig. 7 and looking in the direction opposite to the direction of thearrow.

This invention relates to seat cushions and having spaced relativelymovable frame members formed of spring wire and connected by means whichserve to support the edge pieces of the cushion.

As shown in the drawing the cushion comprises a lower frame 1 and. anupper frame 2, the lower frame being composed of sheet metal members,joined at their ends by mitered joints. Each lower frame member 3 isformed from a single sheet of metal which is folded to form asubstantially rectangular tubular member having inwardly extendingengaging flanges 4, a lower surface 5, in which there is formed atapered slot adapted to receive a t'ackin strip 6, and a flat uppersurface 7. On t e flanges 4 are secured the pressed metal cross piecesor slats 8 upon which are placed supporting springs9, while upon theupper surfaces 7 connected by clips 17 which permit-relative movement ofthe members. The clips, in the construction shown in Fig. 1, rest uponthe upper surfaces of the members 15 and 16 and have their ends bentaround so as tosecure the clips in engagement with the members. Theclips 17 adjacent to the spring caps 12 are secured by spot welding orotherwise to a flange 18 on the flat portion 13. As shown in Fig. 2the'flange 18 projects downwardly so that when secured to the springcaps 12 the upper frame tilts outwardly with the outer frame member '15lower than the inner frame member 16. Resting on the spring caps 12along the side edges are spring strips 19 which are secured to thespring caps 12 and springs 10 in any desired manner as by therivets (notshown) which secure the springs 10 to the spring caps 12. The springstrips 19'extend to theinner frame" member 16 and are secured thereto bybeing passed beneath and bent around the member 16 as shown in Fig. 5.

on the-spring caps 11 are placed spring strips 20 which are secured tothe spring the ca s 11.

caps in any desired manner as by the rivets (not shown) Which secure thesprings 9 to The spring strips 20 extend over t e frame 2 and aresecured to the frame 2 by having their end portions bent around theouter frame member 15 as shown in Fig. 3. Where the s ring strips 20pass over the frame 2 the c ips 17 are omitted and the spring caps 12have the flan es 18 and portions 14 in engagement wit the spring strip20 and secured thereto in any desired manner. I

The spring strips 20 and caps 11 are covered-with the usual webbingcovering 21 over which is placed the covering 22 of duck or othersuitable material which extends over all the springs and is brought downto the lower frame 1 so as to be secured to the tacking strips 6. To thecovering 22 there are stitched a pair of strips 23 which provide spacesin which is'placed a stufling 24 of tow, hemp or other suitablematerial, the strips 23 being so positioned on the covering 22 that thestufiing 24 will rest upon the clips 17 thus forming edge strips alongthe front and rear edges of the cushion. Between the edge strips thereis placed an u holstery piece 25 of hair felt or other suita le materialwhich is made longer than the length of the seat so that its ends may belapped or folded back as at 26 in Fig. 2 to form edge] pieces resting onthe clips 17. The portions folded back at 26 and the stufiing 24together form edges extending about the entire periphery of the cushionand serve to retain the hair stufling 27. Over all is stretched theusual muslin cover 28 and outside cover 29 of plush or other materialthe ends of which are brought down and secured to the tacking strips 6.

In the modified construction shown in Figs. 7, 8, 9 and 10 the upperframe 2 comprises the spaced wire rectangular members 15 and 16 whichare joined by the clips 30. The clips 30 may be short as are the clips17 shown in Fig. 1 or they may be of greater length as shown in Fig. 7and as shown in Fig. 10 they extend beneath the frame members 15 and 16and have their outer ends bent around the frame members while theircenters are bent up between the frame members to form engaging surfacesupon which rest the sprin strips 31 which engage the spring caps 12 othe end rows of springs 10 and the spring strips 32 which are secured tothe spring caps 11 on the springs 9. The spring caps 12 have the flanges18 which engage beneath the upwardly bent portions of the clips and theoffset portions 14 which engagewlth the covering piece 22. As in theprevious construction, the offset portion 14 of the spring caps 12 alongthe front and rear edges of the cushion engage with the spring strips32. Over the spring strips 32 are placed the coverings 21 and 22, thecovering 22 having the strips 23 secured thereto so that the stufling24will rest upon the clips 30, and on the covering 22 is placed theupholstery piece 25, the hair stufling 27 and the coverings 28 and 29 asin the other modification.
